ID   EXBB_NEIMC              Reviewed;         220 AA.
AC   P95375;
DT   15-DEC-1998, integrated into UniProtKB/Swiss-Prot.
DT   01-MAY-1997, sequence version 1.
DT   25-MAY-2022, entry version 60.
DE   RecName: Full=Biopolymer transport protein ExbB;
GN   Name=exbB;
OS   Neisseria meningitidis serogroup C.
OC   Bacteria; Proteobacteria; Betaproteobacteria; Neisseriales; Neisseriaceae;
OC   Neisseria.
OX   NCBI_TaxID=135720;
RN   [1]
RP   NUCLEOTIDE SEQUENCE [GENOMIC DNA].
RC   STRAIN=8013.6 / Serogroup C;
RX   PubMed=9006036; DOI=10.1128/jb.179.3.805-812.1997;
RA   Stojiljkovic I., Srinivasan N.;
RT   "Neisseria meningitidis tonB, exbB, and exbD genes: Ton-dependent
RT   utilization of protein-bound iron in Neisseriae.";
RL   J. Bacteriol. 179:805-812(1997).
CC   -!- FUNCTION: Involved in the TonB-dependent energy-dependent transport of
CC       various receptor-bound substrates. Protects ExbD from proteolytic
CC       degradation and functionally stabilizes TonB (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: The accessory proteins ExbB and ExbD seem to form a complex
CC       with TonB. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC   -!- SIMILARITY: Belongs to the ExbB/TolQ family. {ECO:0000305}.
